We look at the division of 93609129 by 31 
Let's see how many times 31 fits into 93609129.

Advancing to step 1:
When dividing 9 by 31, we get 0 with a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Include the next digit (3) from the dividend after 9, then repeat: 93 / 31

Step 2:
If we divide 93 by 31, we get 3 and a remainder of 0.
Write down 3 as next digit of the result. 
Result so far: 3.0
Subtracting 93 from 93 leaves us with 0.
Take the next digit (6) from the dividend and append it to 0, then repeat: 6 / 31

Going ahead to step 3:
31 goes into 6 0 times with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 30.0
Subtract 0 from 6 to get 6.
Append the next digit (0) from the dividend to 6 and continue with: 60 / 31

Moving on to step 4:
If we divide 60 by 31, we get 1 and a remainder of 29.
Write down 1 as next digit of the result. 
Result so far: 301.0
If we subtract 31 from 60, we get 29.
Bring next digit (9) of the dividend behind the 29 and repeat the process: 299 / 31

Let's proceed to step 5:
If we divide 299 by 31, we get 9 and a remainder of 20.
The number 9 becomes the next digit in our result. 
Result so far: 3019.0
Subtract 279 from 299 to get 20.
Fetch the next digit (1) from the dividend, attach it to 20 and continue: 201 / 31

Step 6:
If we divide 201 by 31, we get 6 and a remainder of 15.
The number 6 becomes the next digit in our result. 
Result so far: 30196.0
The remainder is 15 after subtracting 186 from 201.
Take the next digit (2) from the dividend and append it to 15, then repeat: 152 / 31

Step 7:
152 divided by 31 is 4 with a remainder of 28.
The next digit of our result is 4. 
Result so far: 301964.0
If we take 124 away from 152, we end up with 28.
Fetch the next digit (9) from the dividend, attach it to 28 and continue: 289 / 31

Advancing to step 8:
If we divide 289 by 31, we get 9 and a remainder of 10.
The next digit of our result is 9. 
Result so far: 3019649.0
Deduct 279 from 289 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 9:
31 can be fit into 100 3 times, resulting in a remainder of 7.
Write down 3 as next digit of the result. 
Result so far: 3019649.3
Subtract 93 from 100 to get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Advancing to step 10:
The number 31 fits into 70 2 times, leaving a remainder of 8.
Record the quotient 2 as the next digit in the result. 
Result so far: 3019649.32
Subtract 62 from 70 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 11:
When dividing 80 by 31, we get 2 with a remainder of 18.
The number 2 becomes the next digit in our result. 
Result so far: 3019649.322
If we subtract 62 from 80, we get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

In conclusion, the division gives 3019649.322 with a balance of 0.0018.
